An upper splash plate, a middle splash plate and a lower splash plate are provided in the nozzle body from top to bottom. A primary water sprinkling hole is provided on the connecting head. The upper splash plate and the middle splash plate are respectively provided with secondary water sprinkling holes and tertiary water sprinkling holes. An arc-shaped water baffle is connected to the edge of the upper splash plate. The upper surfaces of the upper splash plate and the middle splash plate are both in a spherical crown structure protruding upward. The aperture sizes of the primary water sprinkling hole, the secondary water sprinkling hole and the tertiary water sprinkling hole decrease in sequence and the three water sprinkling holes are coaxially arranged. The lower splash plate is in a conical structure with a small upper portion and a large lower portion.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] As one of the most important heat dissipation components of a cooling tower, the installation of the filler is restricted near the tower wall due to factors such as concrete beams and columns. Part of the water from the nozzles near the tower wall will be sprayed onto the tower wall, causing this part of the spray water to flow directly into the cooling tower collection pool without being dissipated through the filler, adhering to the tower wall, affecting the overall heat dissipation effect of the cooling tower.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] In view of the defects in the prior art, the utility model provides a wall flow modified cooling tower to solve the problem that in the traditional cooling tower, due to reasons such as concrete beams and columns, the installation of fillers near the tower wall is restricted, and part of the water from the nozzles near the tower wall will be sprayed onto the tower wall, resulting in this part of the spray water not being dissipated through the filler, but directly flowing into the cooling tower collection pool along the tower wall, affecting the overall heat dissipation effect of the cooling tower.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A wall flow modified cooling tower comprises a tower body, wherein a water distribution device and fillers are arranged from top to bottom in the tower body, a guide plate is arranged on the inner wall of the tower body between the water distribution device and the fillers, and the lower end of the guide plate extends obliquely to above the fillers.

[0011] As an optimized solution, the upper end of the guide plate is vertically fixed with a fixing plate that fits the inner wall of the tower body.

[0012] As an optimized solution, the fixing plate is fixed to the inner wall of the tower body by expansion bolts.

[0013] As an optimized solution, a waterproof soft material block is provided between the fixing plate and the inner wall of the tower body.

[0016] As an optimized solution, a water collecting device is provided in the upper area of ​​the tower body located above the water distribution device.

[0017] As an optimized solution, a water collecting pool is provided at the bottom of the tower body.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] It can effectively improve the situation where the nozzles close to the tower wall spray onto the cooling tower wall. The hot water close to the tower wall can be diverted to the filler using the guide plate, so that the heat dissipation effect of the hot water at the wall flow is better, thereby improving the thermal performance of the entire tower.

[0025] like Figure 1 and Figure 2 As shown, the wall flow modified cooling tower includes a tower body, in which a water distribution device 3 and a filler 4 are arranged from top to bottom, and a guide plate 5 is arranged on the inner wall of the tower body between the water distribution device 3 and the filler 4, and the lower end of the guide plate 5 extends obliquely to the top of the filler 4.

[0026] The guide plate 5 is an inclined plate or an arc-shaped plate.

[0027] The upper end of the guide plate 5 is vertically fixed with a fixing plate 7 which is in contact with the inner wall of the tower body.

[0028] The fixing plate 7 is fixed to the inner wall of the tower body by means of expansion bolts 9 .

[0033] A water collecting pool 6 is provided at the bottom of the tower body.

[0034] The working principle of this device is:

[0035] When the cooling tower is in operation, the circulating water, under the action of the water distribution device 3, sprays the spray water evenly on the filler 4, realizes heat exchange with the cold air, and achieves the purpose of heat dissipation; near the nozzle at the tower wall, there is a situation that part of the water is sprayed on the wall of the tower body, and directly flows into the water collection tank 6. Under the action of the guide plate 5, part of the circulating water sprayed on the tower wall by the water distribution device 3 is diverted to the filler 4, achieving a better heat dissipation effect. According to on-site measurements, the performance is improved by about 3%;
